OVERFLOW-TRAP.

SPECIFICATION forming part of Letters Patent No. 639,610, dated December19, 1899. Application filed October 18, 1898. Serial No. 693,911. (Nomodel.)

To @ZZ whom, it may concern,.-

Bc it known that I, FRANK A. RADCLIFFE, residing at Cleveland, county ofCuyahoga,

' and State of Ohio, have invented certain new and useful Improvementsin OverfloW-Traps5' and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in overflow-traps, and especiallyto that type of overflow-traps wherein a glass receptacle for containinga liquid for forming a seal is suspended within an outer casing.

With this object in view my invention consists in forming a combineddevice comprising a gasket for the outer casing and means for suspendingthe glass receptacle within the outer casing and preventing thesiphoning of the liquid contained in the glass receptacle.

My invention also consists in certain features of constructions andcombinations of parts, which will be hereinafter described, andespecially pointed out in the claims.

In the drawings, Figure I is a view in central vert-ical section of anoverflow-trap embodying my invention. Fig. II is a horizontal sectionalview taken through the trap above the flange E'.

My improved trap, as illustrated in the drawings and to be hereinafterfully set forth, is an improvement upon a patent, No. 565,565, grantedto me August Il, 1896.

In the drawings, A represents an outer globular or spherical shellcomposed, preferably, of two sections, the lower section provided withan externally-screwthreaded flange aand Jthe upper section B forming thecap or cover of the trap and having an annular flange b internallyscrew-threaded for engaging the external screw-thread ce. At the upperend of the cover B the inlet-pipe C is secured in any suitable manner,so as to form a tight joint with the aforesaid cover and extenddownwardly to a point at or near the lower part of said casing. Theinlet-pipe O is provided at a point about centrally of the casing withan outwardly and downwardly inclined deflector C for the purpose ofcheck-l ing the current of the fluid during its passage through thetrap.

A discharge-pipe may be secured in any approved manner to the flangeva.' of the discharge-opening A.

In the respects and features above set forth the construction of my trapis very similar to that set forth in my previous patent hereinabovereferred to with the exception that the lower portion of the sphericalshell A is in the present case preferably formed of one piece. Mypresent improvement upon my previous patent may be described as follows:

D represents the inner shell, which is formed of vitreous material,preferably of glass, and the inlet-pipe C, which is supported in thecover B, extends downwardly centrally through the inner shell D to anopening in said shell, so as to discharge, preferably, in closeproximity to the bottom of said shell.

Inasmuch as it is essential that the inner shell be supportedapproximately centrally within the outer shell and be suspended abovethe bottom of the same, I have provided a rnetallic holding or clampingdevice E, which consists of an annular flange E, which is supported uponthe upper portion of the flange ot and forms a metallic gasket. Thisflange E' is provided with arms e e e, which are preferably formedintegral therewith. The function of the arms c e e is to connect theflange E with the downwardly and inwardly inclined deiiector E2, whichacts in conjunction with the downwardly and outwardly inclined deflectorC for the purpose of deflecting the liquid rushing up through the innershell during the passage of the liquid through the trap and compel saidliquid to overflow in a slow and gentle manner and not rush out, whichmight result in siphoning the trap. It will be noticed in thisconnection that the inwardly and downwardly projecting deflector E2 isformed separate and distinct from the inner shell D and is preferablyformed integral with the flange E and arms e e c. rlhe inner shell D issecured in position by means of clips e e c, (three or more,) whichengage an annular beading or flange d, formed on the upper end or edgeof the shell D. Other suitable means may be employed for secu ring theinner shell to the downwardly and inwardly projecting flange ELL-such,for instance, as screws or the like engaging the clips e by means of ascrew- IOO thread in said clip and securing the inner shell D byengaging the same underneath the bead or liange cl. V

F represents a gasket, of rubber, leather, or composition, which forms aseal above flange E and between it and the cover B.

As hereinbefore stated by me, any number of arms e e e and clips c' c emay be employed without departing from my invention, and while I haveset forth in this specification and illust-rated in the drawings certainconstrue-- of metal,th us render-in g the trap useless. This is theresult of forming the water seal within said inner shell, whereby thewater or fluid is always in contact with said inner shell. The otherportions of the trap may be formed of metal without being affected.

The operation of my trap is as follows: The iuid passes throughinlet-pipe Cto the bottom of the inner shell D and from thence passesupwardly and is checked by deflectors C and E and then passes throughthe annular space between the aforesaid deiiectors, over the top of theinner shell D, and into the space between the inner shell and outershell, and

thence out through the orifice in the bottom' of the outer shell.

What I claim is- 1. In an overflow-trap of the type set forth, thecombination with a metallic casing and a glass receptacle adapted to besuspended in said casing, said casing comprising a body portion and acover therefor and having an vopening in its top and bottom; of acombined gasket and device for suspending said glass receptacle in saidcasing so as to leave space for the passage of water from saidreceptacle through said casing, and checking the ow of water from saidreceptacle, said gasket and device being formed from a single piece ofmetal and comprising a flat annular portion adapted to fit between thebody portion of the casing and its cover, a perforated portion forspanning the space between the inner wall of the casing and thereceptacle, a hollow con ical-shaped portion adapted to fit tightlywithin the top of the receptacle, forming a deflector therefor; and earportions for engaging with the receptacle,substantially as described andfor the purpose set forth.

2. In an overflow-trap of the type set forth, the combination with acasing and a receptacle adapted to be suspended therein,said outercasing having an opening in its top and bottom and comprising a bodyportion and a cover therefor; of a device for suspending said receptaclein said casing, and checking the flow of waterfrom said receptacle, saiddevice comprising a broad metallic band adapted to fit within the top ofthe receptacle, earpieces projecting downwardly from the upper edge ofsaid band and adapted to engage with the rim of the receptacle and armsor supports projecting outwardly from the upper edge of the said bandand adapted to rest upon the edge of the body portion of the casing,substantially as described and for the purpose set forth.

3. In an overflow-trap of the type set forth, the combination of ametallic casing, comprising a body portion and a cover therefor; of aglass receptacle adapted to be suspended in said casing so as to leave aspace between said receptacle and the inner wall of said casing, saidreceptacle having a beading around its upper edge; of a gasket adaptedto itbetween the body portion of the said casing and its cover, saidgasket being provided with arms for spanning the space between the saidreceptacle and the inner wall of the said casing; and of a deilectoradapted to fit within the top of the said receptacle and check the iiowof water from said receptacle, said deflector being connected totheaforementioned arms, and having earpieces for engaging with the beadingaround the upper edge of the glass receptacle, substantially asdescribed and for the purpose set forth.
